Stealing customers’ data still seems all too easy
AFP
UNTIL recently TJ Maxx clothes shops were best known for a rapidly-changing
assortment of brand-name clothing at rock-bottom prices. Now TJX, the American
parent company that operates TJ Maxx (TK Maxx as it is known in Britain)
and a clutch of other chains in 2,500 shops in America and elsewhere, may
be better known for letting slip its customers’ credit- and debit-card
details in bulk. This week details were released of a huge security breach
that first cam to light late last year (the company first admitted it had
a problem in January). Hackers had apparently gained access to the card
details of 45.7m customers.
Shamefaced spokesmen have tried to look on the bright side. This may be the
worst instance, ever, of data theft, but TJX reckons three-quarters of the
stolen details were too old to be of any use to criminals. But who knows
? The company concedes it is unsure of the full extent of the theft. Its
computer systems were first breached in July 2005 and much of the data it
had stored was, in time, routinely deleted, possibly after it had been pinched
. That makes it impossible to be sure precisely what went astray and when
.
Not much evidence exists that the stolen data led to more crime. Reports
of criminal use of the stolen information have come from as far afield as
Sweden and Hong Kong. But few arrests have resulted from the fraudulent
use of the stolen information. Investigators say that six people arrested
in Florida last week were using credit-card numbers from TJX’s database
to obtain jewellery and electrical goods worth around $1m. But doubts remain
over whether the case is connected to the information heist. Banks have
done their bit, replacing cards that customers used in transactions with
the company.
Although the damage from this particular instance of cybertheft seems limited
, the general problem is vast. Past American government estimates put losses
from data theft and its more sinister counterpart, identity theft, at some
$50 billion a year. And each month brings further news of the potential
leak of personal information. In the two years up to last December some estimates
reckoned that 100m records had been “compromised” in data breaches in
America.
Data can easily fall into the wrong hands. In December the University of
California said that hackers had accessed the records of 1m former students
and staff (educational institutions appear particularly vulnerable to cybertheft
). The same month Aetna, a big health-care provider, said that burglars had
made-off with back-up tapes containing the details of thousands of customers
, among a haul of more traditional booty. Again in December, Boeing said
that a laptop had gone missing from an employee’s car. The computer held
the personal details of 382,000 former and present employees.
American firms and institutions seem particularly lax at safeguarding private
information. The European Union’s data-protection directive has encouraged
firms in Europe to take the issue more seriously. In America firms have
little incentive to do so. Carelessness brings few penalties other than a
blow to a corporate reputation that may soon pass. And no system can ever
be made completely secure. In the race between security experts and hackers
, the latter always seem one step ahead. And public clamour for action has
failed to translate into federal legislation.
Last year Congress did try to make life tougher for cybercriminals, but then
failed to agree on new data protection measures. In January a new bill was
introduced that would at least insist that customers whose data has been
filched must be told. But the raising of encryption standards, which might
prevent hackers or laptop thieves getting at sensitive information, is not
addressed. Several states, with California at the forefront as usual, have
brought in their own legislation on notification and other measures that
would make it harder for criminals to profit from identity theft. But, for
now, American businesses are taking few extra precautions to prevent wholesale
scams.
